Identify what is wrong. In recent years, the numbers of cell phones and the numbers of pirates have both increased, so there is a correlation, or association, between those two variables. Therefore, pirates cause increases in cell phones. Choose the correct answer below. O A. The correlation, or association, between two variables does not mean that one of the variables is the cause of the other. Correlation does not imply causation. O B. The data on the numbers of pirates and cell phones are sample data, and cannot be used to make conclusions about the populations. OC. The direction of the causal relationship is reversed. Cell phones cause increases in pirates. O D. The number of pirates cannot be accurately measured.
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
